Abstract: PURPOSE: To prevent noise due to the idle rotation of a pump when the remaining water of a bath tub is detected by stopping the pump when the detecting information of no water flow is received from a water flow detecting means before a prescribed time is measured. CONSTITUTION: A pump control means 2 drives a pump 1 until the lapse of time measured by a timer means 5 reaches a prescribed time, under a condition in which a water flow is continuously detected by a water flow detecting means 3, and stops the pump 1 when it receives the detecting information of no water flow by the water flow detecting means 3 before the prescribed time is measured. A remaining water deciding means 4 decides that water remains when the water flow detecting means 3 continuously detects the water flow till the lapse of the prescribed time, and that water does not remain when the water flow detecting means 3 detects no water flow before the lapse of time reaches the prescribed time. Accordingly, the water of a bath tub does not circulate and when water remaining in a drain pipe is drained, the pump is stopped, the pump is not idly rotated.  Thus, the generation of noise can be prevented.
